Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

There's no font for the OT2 encoding in the MinionPro family, I'd say.

@egreg, according to the Documentation of MinionPro there is an OT2 encoding, but may be it has not been installed, for FontPro there is a feature --cyrillic

If that is indeed the case, then how to I install the OT2 encoding?

First, make sure that there are no files named OT2MinionPro*.fd in ...\MikTeX\tex\latex\MinionPro. If that is the case, then take a look at the FontPro site, but first uninstall your current version to avoid conflicts. (btw, use @name to notify other commentators)
